project results

  • Parametric modelling enables the design and testing of multiple energy island design ideas

  • Innovative two-step sea defences reduce the need for onshore revetment armour 

The Challenge

Royal HaskoningDHV was asked to design an island based on a rubble mound. The design would be compared with caisson-based solutions designed by other firms.

The solution

Parametric modelling was used to explore and compare many different designs to inform the most effective and suitable solution. The process revealed numerous challenges and opportunities. 

Modelling revealed that one side of the island would be the most heavily attacked by the harsh conditions of the North Sea. Royal HaskoningDHV identified that two stages of defence would deliver the most effective protection for the island; an approach which reduced the size of onshore defences. 

First, an offshore emerged breakwater would partly dissipate the waves, with the island protected by secondary, onshore revetments.

Extensive modelling showed that in normal conditions the breakwater would dissipate most of the waves, creating a shallow, sheltered channel between the breakwater and the island. 

The Outcome 

The client was pleased with the level of detail and innovation demonstrated in the proposed solutions, and the open manner of discussion and communication concerning the challenges and opportunities.
